I just noticed that iredadmin-PRO is not deleting the MailDir in /var/vmail/vmail1/<domain>/..... when a user is deleted in iredadmin-pro.

It appears if I create the username Juvix, and then send an email to myself, it will auto-create a MailDir called juvix-2012.07.30....(date). If I go ahead and delete the user and then re-create the same user, a new folder is created with a new creation date. The old MailDir along with the e-mails never get deleted.
